# revns: The fitness operating system your AI can drive.

revns turns your objectives into a daily plan. Track any discipline in one score, get a morning brief on what to do next, and let Claude, ChatGPT or any MCP client log, plan and coach for you.

## What it does

- Log training, sleep, meals and gut health in one line or one tap.
- One day score across six pillars: train, move, sleep, recover, fuel, mind.
- A morning brief and a seven-day plan built from your own data and food preferences.
- Couples, friends and team challenges with two-sided consent.
- An MCP server so Claude, ChatGPT and other assistants can read and write your training data.
- Health data encrypted at rest with a per-user key.
